Deafgal--we discussed sign language, and we actually used SOME sign with both boys (even before we knew they had hearing loss.) Thankfully, they have both adapted wonderfully to the hearing aids, and with the aids, they both test out at normal hearing. I think signing may be an option in the future, just to enrich, but we aren't currently working on it.
Mummyruston--big hugs, I know that can be hard to accept. The great news is that your little guy will become accustomed to the hearing aids and know no different since he's being fitted at such a young age. That's wonderful! Our baby was fitted at 5 months, and our oldest was 5 years. Like I just said, they have both adapted wonderfully to wearing them. The 5 year old absolutely loved them immediately. The baby went through a phase of trying to yank them out and eat them lol. We had to keep a hat on him for several months, and now he acts like he doesn't even know they're there.
We are still so new to this journey, but I can tell you that after the initial shock, it has been an unbelievably positive blessing. It is hard, and I know there will be ups and downs. (The 5 year old starts kindergarten tomorrow, and I'm up worrying and praying no one makes fun of him for wearing them, etc.) But to see their little world's open up has been astounding. And now we are to the point where it is as simple as putting on a pair of glasses in the morning. I hope you have a wonderful experience with your little guy--like I said, I'm totally new to this as well, but I'm here if you ever need to talk!
